Inverter Technology
The inverter driven compressor is designed to run at various input
power frequencies (Hz) which controls the compressor’s motor
speed.
Even Temperature – The control package, including the inverter,
monitors the outdoor and indoor temperatures as they relate to the
selected indoor set point and adjusts the compressor speed to match
the load and keep the system operating continuously rather than
cycling and creating temperature swings. This translates to higher
comfort levels for the occupants.
Rapid Pull Down/Warm−Up – Comfort is increased by the
inverter system’s ability to ramp up the compressor speed enabling
the system to reach the user selected room temperature set point
quicker.
Humidity Control – Running the system for longer periods and
continuously varying the compressor speed enhances the humidity
control.
Individual Room Comfort
Maximum comfort is provided because each space can be
controlled individually based on the usage pattern.
Low Sound Levels
When noise is a concern, ductless systems are the answer. The
indoor units are whisper quiet. There are no compressors indoors,
either in the conditioned space or directly over it, and there is none
of the noise usually generated by air being forced through the
ductwork.
When sound ordinances and proximity to neighbors demand quiet
operation, the 38MGR unit is the right choice. With the inverter
technology, these units run at lower speeds most of the time
resulting in reduced sound levels.
Inverter Technology – Enhanced Economical
Operation
Ductless systems are inherently economical to operate. Individual
rooms are heated or cooled only when required, and since the air is
delivered directly to the space, there is no need to use additional
energy to move the air in the ductwork. This economical operation
is enhanced further when the inverter system output matches the
load resulting in a more efficient system.
Easy−To−Use Controls
The multi−zone systems have microprocessor−based controls to
provide the ultimate in comfort and efficiency. The user friendly
wired and wireless remote controls provide the interface between
the user and the unit.
Secure Operation
If security is an issue, outdoor and indoor units are connected only
by refrigerant piping and wiring to prevent intruders from crawling
through ductwork or wall openings. In addition, since the 38MGR
can be installed close to an outside wall, coils are protected from
vandals and severe weather.
Fast Installation
This compact ductless system is simple to install. A mounting
bracket is included with the indoor units and only wires and piping
need to run between the indoor and outdoor units. These units are
fast and easy to install ensuring minimal disruption to customers in
homes or the workplace. This makes the 38MGR systems the
equipment of choice for retrofit applications.
Simple Servicing and Maintenance
Removing the top panel of the outdoor unit provides immediate
access to the control compartment, providing the service technician
access to the diagnostic LEDs to facilitate the troubleshooting
process. In addition, the draw−thru design of the outdoor unit
means that dirt accumulates on the outside surface of the coil. Coils
can be cleaned quickly from the inside using a pressure hose and
detergent.
On the indoor units, service and maintenance expense is reduced
due to the permanent easy to clean filters. Also, error codes are
displayed on the front panel to alert the user to certain system
malfunctions
Built−in Reliability
Ductless system indoor and outdoor units are designed to provide
years of trouble−free operation.
Both the indoor and outdoor units are well protected. Whenever
the microprocessor detects abnormal conditions, the unit stops and
an error code appears.
Inverter systems provide additional reliability due to the soft start.
This refers to the ability of the inverter to start the compressor
motor using reduced voltage and reduced current. This feature is
beneficial from an electrical standpoint (eliminates current spikes)
as well as an overall reliability standpoint due to reduced stress on
all associated system components.
